A surface plasmon polariton sensor consisting of two metal–insulator–metal waveguides and a transverse rectangular resonator is proposed. Both refractive index and temperature sensing characteristics are analyzed by investigating the transmission

The tuning characteristics of non-collinear double QPM (NDQPM)optical parametric amplification with single periodically poled RbTiOAsO 4 (PPRTA) for the pump 526 nm and 800 nm have been investigated theoretically. The double phase matching can be rea

The properties of optical parametric amplification (OPA) based on non-collinear double quasi-phase matching (NDQPM) with single periodically poled KTP (PPKTP) have been investigated theoretically. The NDQPM includes two different non-linear processes

We repot simultaneous optical parametric amplifiers (OPA) and amplitude modulation of signal pulse in a monolithic periodically poled KTP (PPKTP) by electrically controlling the relative phase between the pump, signal and idler waves in a KTP dispers

We present simultaneous phase matching of optical parametric oscillator (OPO) and difference frequency generation (DFG), using a noncollinear interaction in periodically poled crystal with single grating. Selecting proper grating period Λ and titled

In an anisotropic positive index media the tangential components of Poynting vector S and that of wavevector k can have the opposite signs under certain conditions. The phenomenon is called as the anomalous negative refraction. The negative refractio

Continuous tunable mid IR generation is analyzed by difference frequency generation (DFG) in an optical parametric oscillator (OPO). The periodically poled KTiOPO4(PPKTP) crystals are used for DFG of position tuning, temperature tuning and noncolline

A model of three-wave parametric interaction is presented for biaxial crystals, in both type I and type II noncollinear phase-matching (PM) conditions, in which the group velocities of the interacting pulses are suitably linked to each other. To sati
